Abstract:

Floppy Eyelid Syndrome and Prostaglandins
Statement of the Problem: Floppy eyelid syndrome (FES) was originally described by Culberston and Ostler and although common to an oculoplastics practice, the biochemical/biomechanical remain unclear. The phenotype includes long eyelashes, lash ptosis, pigmentary changes, lid laxity, dermatochalasis, blepharoptosis, irritation and discharge often lead to surgical correction.  The syndrome is associated with obstructive sleep apena. As a result of this association, possible etiologies include but are not limited to, connective tissue defects, micro-trauma associated with sleeping on the face. Interestingly, the phenotype of floppy eyelid syndrome is similar to that of prostaglandin associated periorbitopathy. Methodology & Theoretical Orientation: We compared biopsied eyelid tissue of unaffected patients (controls) to those with clinically diagnosised floppy eyelid syndrome. We hypothesize that patients with floppy eyelid syndrome have significantly higher levels of prostaglandin F2 and E2 compared to controls. These measures are made using real-time PCR. Findings: Prostaglandin E2 trended upward in FES patients compared to controls. Prostaglandin F2 trended down in FES compared to controls. Conclusion: Floppy eyelid syndrome seems to be a prostaglandin mediate process. Additional studies are needed to elucidate the precise mechanism.

Abstract:

Infective conjunctivitis is a common self-limiting condition which constitutes around 35% of ocular presentation in general practice. A Cochrane systematic review investigating the effect of antibiotic treatment in the management of bacterial conjunctivitis concluded that the benefits from antibiotic use compared to placebo were marginal. UK national clinical guidelines further state that topical antibiotics should not be prescribed as first line treatment for conjunctivitis. The aim of this audit was to compare the frequency of antibiotic prescription at a busy general practice surgery against the standard set by national guidelines. A retrospective analysis of patients presenting with symptoms and signs of infective conjunctivitis over a period of fifteen months were collated using the SystemOne patient database. 97% of patients included in the study were prescribed topical antibiotics as first line treatment for conjunctivitis. Another 2% of consultations showing evidence of delayed prescribing. Doctor and patient education is important to manage expectations relating to the prescription of antibiotic to reduce unnecessary use. This has implications for reducing antibiotic resistance and improving cost-effectiveness of treatment. Changes implemented at the practice following the audit included updating general practitioners on the latest evidence and national guidelines on infective conjunctivitis management and creating an information leaflet for patients presenting with infective conjunctivitis containing advice on supportive measures to manage their symptoms.

Abstract:

Objective: To determine the effectiveness of wound closure in external dacryocystorhinostomy with use of small skin incision in terms of safety, postoperative skin scar, and patient comfort.

Materials & Method: Study design was prospective, interventional case series. The study was carried out at Department of Ophthalmology, Govt. Lady Reading Hospital, Peshawar from July 2011 to Jan 2013. We have received 100 cases from outdoor department for management and were admitted for external dacryocystorhinostomy. Data was collected on special proforma. Frequencies and percentages were calculated for age, gender and success of external DCR and causes of failure.

Result: The study population comprised of 100 cases. Females were in majority (65%). Old patients more than 40 years were common. Mean age was 60±11years. It is cosmetically better (97%) compared to large skin incision and is satisfactory to patient as well (95%). The success of external dacryocystorhinostomy was (95%).

Conclusion: Closure of external dacryocystorhinostomy skin wound closure using 8-10 mm incision Size is an effective, quick and less traumatic technique. There is less scar formation, bleeding and soft tissue damage. It is cosmetically better compared to large skin incision and is satisfactory to patient as well (95%). There is no effect on failure rate of external dacryocystorhinostomy as well compare to conventional large incision. It is slightly difficult technique as exposure of operating field is small and learning curve of this technique is longer.

Abstract:

Purpose: To describe the clinical features of congenital double elevator palsy (CDEP) and to evaluate different surgical outcomes based on improvements in the primary eye position and ocular motility.

Methods: Sixteen patients with congenital double elevator palsy in Shanghai Children's Hospital were enrolled from July 2014 to January 2017. Forced duction test ( FDT ) was negative in 15 cases. Twelve patients underwent standard Knapp procedure, with or without horizontal squint procedure; one patient underwent Hummelsheim procedure (part of the tendons capsule transposed); two patients underwent augmented Knapp procedure. And one patient had inferior rectus recession in affected eye and superior rectus recession in sound eye, because FDT was positive. Cure standard was defined as final vertical residual deviation ≤10 PD and ≥25% improvement in restriction after operation.

Results: 14 of 16 patients (87.5%) were aligned to with and within 10 prism diopters (PD), all of patients (100%) reached ≥25% improvement in restriction after operation. 5 patients from severe limitation (-3) to only slight limitation (-1) or normal, while improved in the other 11 patients from moderate limitation (-2) to only slight limitation (-1) or normal. One limited case of left “double elevator palsy” was found to have the right “double elevator palsy” as well after the surgery. One case exposed bilateral DVD with esotropia after the surgery. Three patients had binocular vision before and after surgery and none gained it after surgery. No significant surgery complications were observed during the follow-up periods.

TABLE 1. Summary of horizontal rectus muscle transposition procedures (Knapp procedure)

Conclusions: Surgical procedures for CDEP must be individualized according to clinical evaluation and the results of FDT. The results of FDT is of vital importance to choose the appropriate surgical procedure. In addition, CDEP is also needed to early diagnosis and treatment to get the best outcome.

Abstract:

Myopic eyes have a higher incidence of sight-threatening retinal complications compared with emmetropic eyes. Three techniques of refractive surgery are primarily used to reduce severe myopia: corneal refractive techniques (laser in situ keratomileusis,LASIK), phakic intraocular lens (IOL) implantation, and refractive lens exchange (RLE). Each technique has its inherent advantages and disadvantages. Thus, there has been a renewal of interest in the removal of the clear crystalline lens and RLE for the correction of severe myopia.

There have been considerable improvements in surgical technique and in the past 20 years of lens surgery.Phacoemulsification in the capsular bag, use of viscoelastic substances, implementation of sutureless corneal tunnel incision, and better equipment have improved the confidence of cataract surgeons and stimulated new interest in clear lens extraction. These considerations allowed some authors to propose that myopia correction with phacoemulsification and low-power IOL implantation can provide results comparable to those of other techniques.

Despite advances in surgical technique, retinal detachment remains a major concern after RLE for high myopia. Uhlmann et al reported that RLE by phacoemulsification in combination with pars plana vitrectomy (PPV) can reduce the risk of retinal detachment without increasing the risk of other complications, but the main limitation of their retrospective series is the small sample size (eight patients), leading to uncertainty in the conclusions. In this study, our aim was to prospectively evaluate the outcomes and complications of RLE by phacoemulsification with simultaneous PPV in the management of severe myopia.

Abstract:

Purpose: To investigate if presbyopic induce accommodative spasm can be a factor in causing or aggravating dry eye disease. Teaching hospital clinical observational study combines with National Health Insurance database (population data base), 14 years of retrograde data statistical analysis.

Methods: 26193 presbyopic cases and 122959 age-matched control subjects were recruited using the National Health Insurance database. Kaplen-Meier Survival analysis method where use to calculate the hazard rates of these patients becoming dry eye. Using Stratified Cox Proportional Hazard model, confounding factors such as DM, allergic eye, post-surgery status were adjusted and the hazard rate ratio where obtained. 25 patients from dry eye clinic were recruited into the observational study. Dry eye disease was established by traditional methods. Hyperopic/presbyopic corrective glasses were prescribed and patients were follow-up with OSDI (ocular surface disease index) and other dry eye indexes.

Results: The Kaplen-Meier survival curve shows a significant difference between those cases who had presbyopia and those that do not have presbyopia diagnosis. After adjusting for confounding factors with Cox model, the hazard ratio was calculated to be 2.61, showing a significant increase of risk for those that have presbyopia to acquire dry eye disease. In the clinical observational study, full hyperopic corrections and near corrections of glasses were given to the 25 cases, the OSDI shows improvements of symptom signs as soon as 1 week time.

Conclusions: We have statistically proved that the risk of having dry eye disease is much higher if the patient had presbyopic refractive errors. Clinically follow-up of dry eye patients with aggressive treatment of this refractive error such as use of full corrective glasses show an improvement of OSDI. We therefore proposed that presbyopic refractive error can aggravate dry eye disease.

Abstract:

Objective: To compare the outcome of dacryocystorhinostomy surgery with silicone tube intubation and without silicone tube intubation at Geta eye hospital.
Method: A hospital based retrospective comparative case study in which 87 subjects operated for dacryosystitis were analyzed, of which 49 were with silicone tube intubation and 38 were without silicone tube intubation. Study data were obtained from hospital records in which subjects were followed up on one week, one and half month and three months, postoperatively.
Result: On three months of surgery, 72 of 87 (82.76%) were followed up. Of 39 with silicone tube 35 (89.7%) had patent ducts and of 33 without silicone tube 29 (87.9%) had patent ducts on lacrimal syringing which was considered as success of the surgery. Only 4 patients in each group, 10.3% silicone tube and 12.1% without silicone tube had regurgitation of mucous or pus (failure) on lacrimal syringing. Both the group did not differ significantly (p=0.54).
Conclusion: Dacryocystorhinostomy with silicone tube intubation and without silicon tube intubation procedure offer similar efficient outcome.

Abstract:

Evaluating patient’s astigmatic error isn’t just about the shape of the front of the eye anymore. Failure to include posterior corneal curvature in the presurgical cataract calculations can bring unwanted refractive surprises for both patient and surgeon. There’s a fair amount of astigmatism on the posterior surface of the cornea.Using an intraocular lens in which the lens calculation for toricity is based on the anterior cornea alone will lead to an overcorrection in eyes that have with-the-rule astigmatism and under correction in eyes with against-the-rule astigmatism. Posterior corneal astigmatism must be measured and the net astigmatism should be used in the toric lens calculation
