Objective: To compare the clinical profile, systemic risk factors, and characteristics of rhegmatogenous retinal detachment (RRD) in pseudophakic and phakic eyes.
Study design: Cross-sectional comparative study.
Place and duration of study: Armed Forces Institute of Ophthalmology, Rawalpindi from August 2013 to August 2015.
Methodology: A total of 164 eyes (96 pseudophakic patients and 68 phakic patients) with RRD were analyzed. Demographic data and associated known risk factors of study population were acquired. Retinal examination was done by single experienced retinal surgeon using indirect ophthalmoscopy for type of retinal break, location and number of retinal breaks, status of macula, morphological extent of RRD and retinal degenerations. All the findings were endorsed on a pre-devised proforma.
Results: Mean age of patients in pseudophakic and phakic groups was 61.18 ±10.39 and 59.27 ±9.57 years, respectively. Frequency of male patients in pseudophakic and phakic groups was 74% and 57.4%, respectively. Mean axial length in pseudophakic and phakic groups was 23.13 ±2.18 mm and 21.9 ±2.01 mm, respectively. Difference in axial length and gender distribution between two groups was statistically significant (p < 0.05). Difference in frequency of patients with history of hypertension and myopia between two groups was statistically significant (p < 0.05). Characteristics of RRD (type, location and number of retinal breaks, macula status, and extent of RRD) between groups were not statistically significant.
Conclusion: RRD is more common in pseudophakic patients with male gender, increased axial length, myopia, and hypertension.
