Glaucoma › Neovascular glaucoma

Iris Neovascularisation in Neovascular Glaucoma

Fine, abnormal new vessels (rubeosis iridis) appear at the pupillary margin and spread across the iris surface, potentially leading to angle closure and raised intraocular pressure.

Anatomy Optics › Cranial nerves of the eye (CN III, IV, VI)

Third Nerve Palsy (Left)

Ptosis with “down-and-out” position of the affected eye, often associated with diplopia and a dilated pupil in compressive lesions.

Oculoplasty › Dermoid cyst

Dermoid Cyst

Congenital choristomatous lesion composed of skin and adnexal structures, typically presenting as a well-circumscribed, firm mass near the superotemporal orbital rim.

Oculoplasty › Ectropion

Cicatricial Ectropion

Outward turning of the eyelid margin due to cicatricial shortening of the anterior lamella, commonly following trauma, burns, or chronic inflammation.

Pediatric › Childhood ptosis

Congenital Ptosis

Drooping of the upper eyelid present since birth, most commonly due to levator muscle dysgenesis, with reduced levator function and variable severity.

Uvea › Panophthalmitis

Panophthalmitis

Severe, diffuse infection involving all coats of the eye and intraocular contents, typically presenting with marked inflammation, pain, proptosis, and profound visual loss.

Anatomy Optics › Extraocular muscles

Left Sixth Nerve Palsy

Left lateral rectus weakness causing inability to abduct the left eye, resulting in horizontal diplopia that worsens on looking to the left.

Anatomy Optics › Ocular blood supply

Ophthalmological Features of Carotid–Cavernous Fistula

Typical ocular findings include conjunctival chemosis, arterialized episcleral vessels, proptosis, raised IOP, ophthalmoplegia, and retinal venous congestion.

Retina Vitreous › Vitreous hemorrhage

Asteroid Hyalosis

Multiple yellow-white, refractile calcium-lipid deposits suspended in the vitreous, producing a characteristic “starry-sky” appearance.

Cornea › Bacterial keratitis

Leucomatous Corneal Opacity with Vascularisation

Dense, white corneal opacity associated with prominent corneal neovascularisation, indicating a longstanding healed corneal disease.

Cornea › Exposure keratopathy

Band-Shaped Keratopathy

Horizontal, band-like deposition of calcium in the superficial cornea, typically involving the interpalpebral zone with a clear interval at the limbus.

Oculoplasty › Eyelid tumors

Squamous Papilloma

Benign exophytic epithelial lesion with a papillary, frond-like surface, commonly arising from the conjunctiva or eyelid.

Anatomy Optics › Conjunctival anatomy

Grade 3 Pterygium

Advanced pterygium extending onto the visual axis, with significant corneal involvement and potential visual impairment.

Ocular Trauma › Intraocular foreign body

Corneal Iron Foreign Body

Metallic foreign body embedded in the corneal stroma with surrounding rust ring, typically following high-velocity occupational trauma.

Ocular Trauma › Blunt trauma

Dislocated Intraocular Lens

Intraocular lens displaced from its intended position due to capsular or zonular instability, with abnormal lens position and possible visual disturbance.

Uvea › Tubercular uveitis

Keratic Precipitates in Arlt’s Triangle

Keratic precipitates arranged in a triangular distribution over the inferior corneal endothelium, with larger deposits inferiorly.

Oculoplasty › Eyelid tumors

Xanthelasma

Soft, yellowish, flat or slightly raised plaques composed of lipid deposits, typically occurring near the medial canthus of the eyelids.

Cornea › Exposure keratopathy

Spheroidal Degeneration

Multiple yellowish, translucent, globular deposits in the superficial cornea, typically involving the interpalpebral zone.

Anatomy Optics › Macula and fovea anatomy

Full thickness macular hole

Full-thickness defect of the fovea extending from the internal limiting membrane to the retinal pigment epithelium.

Anatomy Optics › Retinal anatomy

Gyrate atrophy

Multiple sharply demarcated, scalloped areas of chorioretinal atrophy, typically beginning in the mid-periphery and progressively extending toward the posterior pole.

Pediatric › Congenital corneal opacities

Buphthalmos in Congenital Glaucoma

Enlargement of the globe due to elevated intraocular pressure during infancy, with prominent corneal enlargement and thinning.

Anatomy Optics › Corneal anatomy

Munson’s Sign in Keratoconus

V-shaped protrusion of the lower eyelid on downgaze due to the conical protrusion of the cornea.

Cornea › Herpes simplex keratitis

Dendritic Ulcer – Herpes Simplex Keratitis

Branching epithelial corneal ulcer with characteristic terminal bulbs, typical of HSV epithelial keratitis.
