Reversible no light perception in patients with hyphema

ABSTRACT

One hundred cases of hyphema were studied from 1989-91. Seventy-six% of patients were under 20 years of age. Trauma was the prevalent cause of hyphema [94%]. 42% of the patients had intraocular pressure above 21 mm Hg. Along with hyphema, we observed vitreous hemorrhage [32%], corneal laceration [20%], macular edema [16%], traumatic lens opacity [12%], conjunctival laceration [8%], retinal detachment [RD] [5%], optic atrophy [5%] and scleral laceration [2%]. 62% of patients had a visual acuity between light [LP] and hand motion [HM] and 8% were no light perception [NLP] and had +4 reverse Marcus-Gunn [MG]. Two NLP patients whose intraocular pressure [IOP] could not be controlled with medical treatment underwent anterior chamber washout procedure. As a result of this, they gained visual acuity [VA] of 4/10-6/10 and their reverse MG was resolved. No significant complications such as vitreous hemorrhage or lens opacity were observed. Since hyphema alone can cause NLP and reverse MG, we suppose that all NLP patients with hyphema whose IOP are not under control with full medical treatment can be a candidate for the above mentioned surgical procedure
