A Unique Case of JOAG With Lamellar Ichthyosis With Rickets: A Case Report and Review of the Literature.

PURPOSE: Ichthyosis is known to have ocular associations such as blepharitis, hypertrophic conjunctivitis, corneal vascularization, ectropion, lagophthalmos, etc. However, no reports of its association with glaucoma are there, to the best of our knowledge. We report a unique case of juvenile open-angle glaucoma (JOAG) with lamellar ichthyosis. METHOD: A 16-year-old male child presented with a gradual, painless progressive diminution of vision in both eyes over a period of 3 years. Systemic examination revealed stunted body growth with knock-knees, suggestive of late-onset rickets. Generalized dry scaly lesions with erythema, along with hyperkeratosis of the palms and the soles, suggestive of lamellar ichthyosis were present. On ocular examination, the intraocular pressure was 36 mm Hg; optic nerve head examination revealed a horizontally oval disc with near total cupping in the right eye and total cupping in the left eye, with extensive neuroretinal rim thinning and pallor. Gonioscopy showed wide open angles with prominent iris processes. Screening of JOAG-associated genes (MYOC, NTF4, WDR36, and CYP1B1) and ichthyosis-associated gene (TGM1) was performed by the direct PCR-sequencing method. RESULTS: A diagnosis of JOAG with advanced glaucomatous optic neuropathy with lamellar ichthyosis and rickets was made. The patient underwent right followed by left eye trabeculectomy with 0.2 mg/dL MMC (for 1 min). Postoperatively, the intraocular pressure was 8 mm Hg at 1 week, and 12 to 14 mm Hg at the 6-week, the 3-month, and the 6-month follow-up, and the visual acuity was maintained in the right eye. No mutations in MYOC, NTF4, WDR36, CYP1B1, and TGM1 were observed in the patient and his family. CONCLUSIONS: An association of glaucoma with ichthyosis should be kept in mind. Therefore, a detailed baseline ocular examination in children with ichthyosis is required, as early detection of glaucoma could prevent irreversible blindness.

Bilateral Sturge-Weber and Phakomatosis Pigmentovascularis with Glaucoma, an Overlap Syndrome.

UNLABELLED: Aim. To report a case of bilateral Sturge-Weber and Phakomatosis pigmentovascularis with secondary glaucoma in a child. Method. CASE REPORT: Results. A 4-year-old male child was referred to us for control of intraocular pressure (IOP). Sleeping IOP was 36 mm Hg in right eye and 28 mm Hg in the left eye. The sclera of both the eyes showed bluish black pigmentation-melanosis bulbi. Fundus examination of both eyes showed diffuse choroidal hemangiomas with glaucomatous cupping. Nevus flammeus was present on both sides of face along all the 3 divisions of trigeminal nerve with overlying hypertrophy of skin and on left forearm. Nevus fuscocaeruleus was present on upper trunk. All skin lesions were present since birth and were stationary in nature. CT scan of head revealed left-sided cerebral atrophy. Intraocular pressure was controlled after treatment with topical antiglaucoma medications. Pulsed Dye Laser has been advised by dermatologist for skin lesions. Patient has been advised for regular follow-up. Conclusion. The two overlapping dermatological disorders and their association with glaucoma are a rare entity. Management should be targeted both for dermatological and eye conditions.
