Triads in Ophthalmology
Triads are usually a combination of three clinical features or signs, often used to describe various clinical conditions or diseases. Here we have compiled some of these triads used in ophthalmology. Care should be taken while interpreting these triads, as many of them were described while reporting the particular clinical entity and are not considered as a tell-tale sign of that entity anymore. For example, Behçet's disease was described as a triad of oral ulcers, genital ulcers and hypopyon uveitis by Huluci Behcet. However, now we know that hypopyon can occur only in one-third of patients with the disease and is not included in diagnostic criteria for the Behçet's disease.
Bálint's Syndrome= Simultanagnosia+ Optic ataxia+ Ocular motor apraxia
Behçet's Disease= Oral ulcers + Genital ulcers + Hypopyon uveitis
Cerebral Whipple's Disease= Somnolence + Dementia + Ophthalmoplegia.
Cone Degeneration= Progressive central acuity loss + Color vision disturbances + Photophobia.
Congenital Glaucoma= Epiphora + Blepharospasm+ Photophobia
Congenital Rubella Retinopathy= Cataracts+ Deafness + Congenital heart disease
Congenital Toxoplasmosis= Retinochoroiditis+ Hydrocephalus+ Intracranial calcifications
De Morsier's Syndrome= Short stature+ Nystagmus + Optic disc hypoplasia
Fechtner's Syndrome= Nephritis+ Sensorineural hearing loss+ Eye abnormalities
Gaucher Disease= Trismus+ Strabismus+ Opisthotonus
Horner's Syndrome= Ptosis+ Miosis + Ipsilateral anhidrosis of the face
Intraoperative Floppy Iris Syndrome=A flaccid iris stroma that undulates and billows in response to ordinary intraocular fluid currents+ A propensity for the floppy iris stroma to prolapse toward the phaco and side-port incisions, despite proper wound construction + Progressive intraoperative pupil constriction despite standard preoperative pharmacologic measures designed to maximize dilation
Kearns–Sayre Syndrome=External ophthalmoplegia + Pigmentary retinopathy + Cardiac conduction block during the first or second decade of life
Lambert–Eaton Myasthenic Syndrome=Muscle weakness+ Autonomic dysfunction+ Hyporeflexia
Miller-Fisher Syndrome=Ataxia+ Ophthalmoplegia+ Areflexia
Ocular Ischemic Syndrome=Midperipheral dot hemorrhages+ Dilated retinal veins + Iris neovascularization
Ocular Tilt Reaction=Skew deviation+ Cyclotorsion of both eyes + Paradoxical head tilt
