13. Holding a book too close or
sitting too close to the
television set is harmful to the
eyes
14. Myth !
kids can actually focus up close without
eyestrain better than adults, so they often
develop the habit of sitting right in front of the
television or holding reading material close to
their eyes. However, sitting close to a TV may
be a sign of nearsightedness.
20. There is much speculation concerning the strong distinctive yellow color
and halos in Van Gogh’s paintings. They may have been due to
xanthopsia, a form of dyschromatopsia that causes the sufferer to have
the impression of seeing things through a yellow filter. This condition
may be caused by early cataract but, in van Gogh’s case, may have been
through intoxication by the digitalis that he was prescribed for mania and
depression.
21. The artist could also have been suffering from glaucoma, and the
halos clearly painted around the stars-Starry night painting—may
have been created under the effect of high interocular pressure
(IOP) spikes
24. Hutchinson's sign
Involvement of the tip of the nose from herpes zoster, a sign taken
to indicate that the eye may be seriously involved by VZV because
of the involvement of the nasal branch of the nasociliary nerve.
29. B Blockers
Beta-blockers reduce IOP by decreasing aqueous production, mediated
by an effect on the ciliary epithelium. In approximately 10% of cases the
response decreases with time (tachyphylaxis), sometimes within only a
few days. There may be limited supplementary effect if a topical beta
blocker is added when a patient already takes a systemic beta-blocker

dimensional, cross-sectional view of the eye and the orbit

39. Johann Friedrich Horner
(27 March 1831 – 20 December 1886) was an ophthalmologist based at
the University of Zurich, Switzerland.
Horner became a full professor of ophthalmology in 1873. After his death
in 1886, his position at the University of Zurich was filled by Otto Haab
(1850–1931).
47. Contrary to his earlier paintings, his later work has
fewer details, the shapes are “blurring”. The cataract related
changes in his lenses reduced their sensitivity to
contrast and light permeability
48. Many of these later paintings verge on the abstract, with colors
bleeding into each other and a lack of rational shape and
perspective
49. The first one was painted when he used his left eye, which had not
been operated on and was affected with cataract: warm colors
red- orange-yellow, are dominating. The second one, painted
when he used his right eye operated for cataract surgery, shows
only cool colors, blue and violet.
51. Hannibal
Hannibal lost one eye due to conjunctivitis seven
months after he had crossed the alps, while wading through
a fetid Etruscan (= Tuscan) Swamp.
53. Forest Whitaker
is well known for his lazy left eye, though in his case, it’s a vision problem as
well. Whitaker says that when he looks up, he can’t see well out of his left eye,
and that the problem might be fixed if his lazy eye is corrected.
55. Pseudopapilledema
(Optic Disc Drusen)
represent apparent optic disc swelling that simulates some features of
papilledema but is secondary to an underlying, usually benign process.
Other causes :
• Tilted optic disc • Peripapillary myelinated nerve fibres • Crowded disc in
hypermetropia
57. Primary Acquired Melanosis
The term primary acquired “melanosis” is inaccurate because the lesion is
characterized by proliferation of conjunctival epithelial melanocytes and not
deposition of pigment – a more appropriate term is “Conjunctival Melanocystic
intraepithelial neoplasia”
60. Occipital Lobe Disorders Related
Phenomena
Riddoch phenomenon
Riddoch and Holmes observed that individuals recovering
from occipital lobe injuries first perceive moving objects
but not stationary ones. The Riddoch phenomenon can
be observed during confrontation field testing by
comparing the patient’s responses to moving and still
targets. More recently it has been shown that rare
patients with uni- or bilateral occipital lesions lose object
recognition but in some instances may have
“blindsight,” an unconscious ability to locate light
sources and detect moving targets in affected fields
69. Optic nerve sheath meningioma is a benign tumour, typically affect
middle-aged women. The prognosis for life is good in adults, although
the tumour may be more aggressive in children.
They are more common in neurofibromatosis type II (NF2).
71. Uveitis of JIA
The uveitis of JIA is particularly dangerous because it is invariably
asymptomatic and must generally be detected by screening with slit lamp
examination. Even during acute exacerbations with +4 aqueous cells, it is rare
for patients to complain, although a few report an increase in vitreous floaters.
Often uveitis may not be suspected until the parents recognize complications
such as strabismus, or an abnormal appearance of the eyeball due to band
keratopathy or cataract. ○ Injection is usually absent even in the presence of
severe uveitis. !!!
75. Lowe (oculocerebrorenal) syndrome is an X-linked recessive (gene:
OCRL1) inborn error of amino acid metabolism with neuromuscular,
renal and other manifestations. Cataract is universal, and microphakia
may also be present. Congenital glaucoma is present in about half of
patients. Female carriers may have visually insignificant cortical lens
opacities
79. Gonorrhea is a venreal
genitourinary tract
infection caused by
Neisseria gonorrhoea,
which capable of invading
the intact corneal
epithelium
N.B. The patient must
be hospitalized if there
is corneal ulceration
N.B. Patients must be
referred to a
genitourinary department
to be screened for
associated chlamydial
infection and contact
tracing.
