Determination Of Association Of Pigmentary Glaucoma With Pigment Dispersion Syndrome.

BACKGROUND: Pigment Dispersion Syndrome (PDS) is an autosomal dominant disorder of white males between 20 to 40 years of age characterized by deposition of pigment on the lens, zonules of lens, trabecular meshwork and corneal endothelium (Krukenberg's spindle) in addition to radial, spoke like transillumination defects in the mid peripheral iris. This study was conducted to determine the frequency of occurrence of Pigmentary Glaucoma in patients with Pigment Dispersion Syndrome (PDS). METHODS: This longitudinal follow up study included patients presenting with Krukenberg's spindle on the endothelial side of cornea and pigmentation of angle of anterior chamber seen on slit lamp examination and gonioscopy. RESULTS: Seventy-two cases of PDS were included in the study, amongst them 63 (87.50%) were males. Mean age was 35.00±6.54 years (range 24-46 years). Forty-seven (65.28%) patients had an IOP in the range of 10-14 mmHg, 22 (30.56%) patients had an IOP in the range of 15-18 mmHg and 3 (4.17%) patients developed an IOP of greater than 19 mmHg. Fundoscopy showed myopic degeneration in 49 (68.06%) patients and optic disc cupping in 3 (4.17%) patients. Four (5.56%) patients had refractive error between +1D to +3D, 9 (12.50%) patients had refractive error between -1D to -4D, 21 (29.17%) patients had refractive error between -5 D to -8 D and 38 (52.78%) patients had refractive error between -9 D to -12 D. Our study showed that one patient having PDS developed glaucoma at 5 years of follow up and three patients developed glaucoma at 14 years of follow up. CONCLUSIONS: On the basis of this study we conclude that early onset primary open angle glaucoma associated with PDS or Juvenile glaucoma associated with PDS might have been mistaken as Pigmentary Glaucoma in Pakistani patients and a distinct entity in the form of Pigmentary Glaucoma may be non-existent.

Visual outcome in patients of keratomycosis, at a tertiary care centre in Larkana, Pakistan.

OBJECTIVE: To study the post-treatment visual outcome of fungal keratitis. METHODS: This prospective study was carried out at Chandka Medical College and Hospital, Larkana, Pakistan, from March 2005 to March 2016. Patients with clinical features of fungal keratitis, with positive corneal scrapings for fungi, and those who followed up for a minimum period of three months after recovery from infection were included.Other causes of infectious keratitis were excluded. The clinical diagnosis of fungal keratitis was based on risk factor identification and characteristic non-specific and specific corneal features. Treatment included antifungal preparations, topical and if necessary systemic, in addition to symptomatic measures. SPSS 20 was used for data analysis. RESULTS: Of the 1,130 patients, 750(66.37%) were males and 380(33.63%) were females. The overall mean age was 39.44±12.46 years (range:16-74 years). After the completion of treatment, 590(52.21%) of the eyes just retained visual acuity of not more than counting fingers and 126(11.15%) patients lost their globe. Patients with remaining corneal opacity needed keratoplasty. CONCLUSIONS: Most of the eyes just retained visual acuity of counting fingers while some patients lost their globe.

Types of Traumatic Lens Dislocations at Larkana.

The objective of this study was to determine the pattern of traumatic lens dislocations presenting at our institute. This may help develop the preventive strategies. The number of cases of traumatic lens dislocations, presented at the Department of Ophthalmology, Chandka Medical College, Larkana, Pakistan, from January 2002 to June 2015, were 59 including 61.02% (n=36) males and 38.98% (n=23) females. Cause of trauma was wood or plant impalement in 35.6% (n=21) cases, cracker blast in 13.55% (n=8) cases, fall on ground in 11.86% (n=7) cases, penetrating injuries with needle, scissors or knife in 10.16% (n=6) cases, road traffic accidents in 10.16% (n=6) cases, sports injuries (cricket ball and gulle danda) in 8.47% (n=5) cases, firearm injuries in 5.1% (n=3) cases, and fist hitting in 5.1% (n=3) cases. Lens was dislocated posteriorly in 33.90% (n=20) cases, anteriorly in 25.42% (n=15) cases, inferiorly in 11.86% (n=7) cases, medially in 10.17% (n=6) cases, laterally in 10.17% (n=6) cases, superiorly in 6.78% (n=4) cases, and a single (1.69%) case of lenticele was seen.

Factors associated with pterygium based on history and clinical examination of patients in Pakistan.

PURPOSE: The purpose of this study was to determine the factors associated with Pterygium, utilizing history and examination. METHODS: In this prospective case series study, a total of 1227 patients with Pterygium presenting at the Department of Ophthalmology, Chandka Medical College Hospital Larkana, Pakistan, from January 1997 to January 2015 were included. A standard proforma containing proposed risk factors was filled in for every patient. Clinical examination was performed on slit-lamp biomicroscope to confirm presence of pterygium. RESULTS: Out of the total 1227 patients, 656 (53.46%) were males, and 571 (46.54%) were females. Mean age ± standard deviation was 53.12 years ± 15.85 years, and the age range was 20-79 years. 1063 (86.63%) patients belonged to areas with hot and dry weather, 421 (34.31%) patients had a positive family history for Pterygium, 740 (60.31%) patients had history of previous exposure to toxic chemicals, and 364 (29.67%) patients had dry eye. CONCLUSION: This study points towards the simultaneous role of multiple risk factors including sun exposure, hot climate, toxic material exposure, familial transmission, and dry eye in association with pterygium.
