BACKGROUND
Secondary glaucoma is an anatomically identifiable abnormality which in turn is an
underlying cause of the events that lead to aqueous outflow obstruction and rise
in the intraocular pressure. This prospective study mainly highlights the secondary
glaucoma with special reference to its proportion, causes and its risk factors in a
tertiary care hospital.
METHODS
This study was a cross sectional study. Patients, who attended the Department of
Ophthalmology after fulfilling the inclusion and exclusion criteria diagnosed with
secondary glaucoma, were included in the study. The study period was from
February 2018 to June 2020. A standard form was filled up for each patient
documenting parameters and findings of various examinations and was evaluated
as per protocol.
RESULTS
Secondary glaucoma was seen in 0.2 % patients who visited during the study
period. Out of 106 patients, males were 50, females were 56, with a male: female
ratio of 1:1.1. The most common cause of secondary glaucoma was lens induced
glaucoma seen in 44.34 % followed by uveitic glaucoma in 20.8 % cases,
traumatic 17.9 %, neovascular 10.4 %, pseudoexfoliation glaucoma 2.8 %,
pigmentary glaucoma 1.9 %, silicon oil induced 0.9 %, and uveitis-glaucomahyphema
syndrome in 0.9 % cases. Around thirty five percent (34.9 %) cases
presented with sudden onset of painful diminution of vision with nausea and
vomiting.
CONCLUSIONS
Secondary glaucoma is still one of the prevalent diseases in this part of country.
Lens induced glaucoma is still the most common cause of secondary glaucoma.
Hypermature cataract, uveitis, trauma and neovascularisation are the different risk
factors.
