Lens-induced glaucoma is not an uncommon entity in low-to-middle income countries,,, where uptake of healthcare may not only be delayed but access to it may be poor, or it may not be affordable. Such glaucoma usually occurs when the cataract becomes mature or hypermature. When a cataract becomes hydrated and intumescent, it can cause angle closure glaucoma (termed phacomorphic). Hypermature cataract, where the cortex is liquefied and the lens proteins leak out through the capsule, typically gives rise to an open angle type of glaucoma (termed phacolytic). A morgagnian cataract is an extreme hypermature lens, where cortex is totally liquefied and nucleus sinks to the bottom. Such a lens is more likely to cause phacolytic glaucoma.
A 68-year-old gentleman presented with progressive “blurred” vision for 5 years and pain for 6 weeks in the left eye. His vision was hand movements with corneal edema, shallow anterior chamber (AC), “mature” cataract [Figure 1]a and IOP of 52 mmHg on 3 topical and oral antiglaucoma medications (AGM) and closed angles on Sussman 4-mirror gonioscopy. IOP responded only partially to stepped-up AGM (34 mmHg); laser peripheral iridotomy was done following which corneal edema resolved, AC deepened [Figure 1]b, and IOP improved (22 mmHg). A morgagnian cataract with a very large nucleus was seen only postdilatation [Figure 1]c.

The fellow eye was pseudophakic (>4 years) with normal vision, IOP, and fundoscopy.
As presentation was delayed, cataract surgery was undertaken along with trabeculectomy; patient wished to defer IOL implantation, as visual prognosis was indeterminate. Postoperatively at last follow-up, vision did not improve and IOP was controlled at 11 mmHg without AGM, but, more importantly, patient became asymptomatic. Fundoscopy revealed a pale and fully cupped disc; therefore, secondary IOL was not undertaken.
| Discussion|| |
Morgagnian cataract occurs in a hypermature state, where the cortex is completely liquefied and has an association with phacolytic glaucoma. However, in this eye, phacomorphic glaucoma occurred, likely due to the extremely large nucleus simulating intumescence. Forward movement of the iris-lens diaphragm due to zonular laxity may have also contributed. Once a cataract is associated with glaucoma, pain ensues due to high intraocular pressure. It is pain in the eye that prompted this patient to seek ophthalmic consultation, albeit in a delayed manner (>6 weeks after its onset). At such late onset, inclusion of trabeculectomy in the surgical plan is mandatory for alleviation of pain. Morgagnian cataract causing phacomorphic angle closure is not reported in the literature.
